MIM

PM post-processing: sintered compacts after further processing according to specific requirements determine of products. Common treatment methods include pressing, maceration, after heat treatment, surface treatment , machining and so on. 1.Repressing For the purpose of improving the physical and mechanical properties of sintered body pressure, including finishing and shaping. Finishing is carried out in order to achieve the desired size of …

1.The method of sintering   Performance of different products and different sintering method (1)According to the raw materials of different classification. Sintering can be divided into unit of sintering, multiple solid phase sintering and multicomponent liquid phase sintering Unit of sintering is the pure metal,(such as ferrite soft magnetic materials and refractory metals ) or compounds (Al2O3, B4C, BeO, MoSi2, etc.) …

1.High degree of complex shape, the additional cost is less 2.Net costs can be reduced or eliminated for machining and finishing processes 3.High material utilization rate, 95% -98% of the material used in the product 4.Several requested features have similar size control 5.Flexibility in composition, microstructure and materials 6.Can wear or toughness requirements of heterogeneous microstructure 7.Good surface quality of …

Function: improve the dimensional stability, elimination of internal stress Category:Heat treatment and Humidity treatment  1.Essence heat treatment:forcing frozen chain slack, solidifying the macromolecular chains are turning to random locations to eliminate internal stress, improve crystallinity, stable crystalline structure, improve modulus, lower elongation. 2.Humidity treatment:Will just release the product into the water, isolated from the air, preventing oxidation. Humidity conditions: 90~110℃ 4H. 3.Post-treatment: size requires more sophisticated parts, you need to make the necessary post-processing. This process is the same as the conventional procedures of heat treatment of metal products.

The application of Metal injection molding technology areas: 1.Computer and auxiliary facilities, such as printer parts, magnetic core, firing pin shaft pin, drive components. 2.Tools, such as drilling, cutting head, nozzle, gun drill, spiral milling cutter, the punch, sleeve, wrenches, electrical tools, hand tools, etc. 3.Household appliances: watch cases, watch fobs, fans, electric toothbrushes, scissors, Golf Club heads, jewelry chain, …

Metal injection molding (referred to MIM) is a new technology of powder metallurgy and plastic molding to combine metal parts,high-volume manufacturing of small rapid development of complex precision metal parts. Production flow diagram of MIM as follows: Flow chart of metal injection molding Mixing process Machine picture Product picture       Feeding: about 60% of metal powder mixed with  40% of binder into …

11.the shape of the powder particles used in powder metallurgy is determined by what? There are roughly what kinds? Due to the different method of preparing the powder, the particle shape is different. Generally have an irregular shape, sheet, polyhedral, dendritic, granular, spherical droplets, fibrous …… 12.What is the powder particle size? Usually determined by what method? Particle size refers …

1.What is powder metallurgy? Powder metallurgy is a manufacturer of metal powders and metal powder (sometimes also add a small amount of non-metallic powder) as raw materials, mixing, shaping and sintering of manufacturing technology of materials or products. It consists of two parts, namely: (1) manufacture of metal powders (including alloy powders, hereafter referred to as “metallic powder”). (2)metal powder …

The difference between powder injection molding and other method which based on molding sometimes can be confused. Molding is often used in the traditional production of powder metallurgy, ceramics and carbides. Molding is the application of technology has longtime been used to form a wide range of materials–ranging from ceramics to pharmaceuticals. Molding use upper and lower punch to suppress …

How do you know if a product is suitable for use in powder injection molding process ? You first need to consider the annual output. From past experience, the powder injection molding for industrial demand from the annual production of 5,000 pieces (such as specialized gun sight) to annual production of 100 million pieces (for example, mobile phone vibrator counterweight). …
